patch for text2pcap on big-endian machines

libz 1.2.3, without POSIX capabilities, without libpcre, without SMI, without
c-ares, with ADNS, without Lua, without Python, without GnuTLS, with Gcrypt
1.2.2, without Kerberos, without GeoIP, without PortAudio, without AirPcap.
Running on SunOS 5.8, with libpcap version 1.1.1, with libz 1.2.3, Gcrypt

Built using gcc 3.4.6.

When the text2pcap -i option is used to create a capture file, and that capture
file is read back with wireshark, it behaves differently on a big-endian
machine such as sparc than it does on a little endian machine like x86. On the
little-endian machine the IP addresses are 10.1.1.1 an 10.2.2.2, but on the
big-endian machine they are 1.1.1.10 and 2.2.2.10.
The problem seems to be the hard coded src_addr and dst_addr values for HDR_IP
in text2pcap.c. I'm sure there are various ways to fix this, but I've
attached a patch that seems to work here.
